Leader’s Hainbuch collet chuck provides three-in-one
With the Mando Adapt and Jaw Adapt system, companies can quickly and effectively transform a standard Hainbuch collet chuck into a mandrel for internal workpiece fixturing or into a large capacity jaw chuck.
Award-winning workholding specialist Leader Chuck Systems offers these two exciting products that add an unrivalled level of flexibility to lathe workholding. Mando Adapt and Jaw Adapt can quickly and effectively transform a standard Hainbuch collet chuck into a mandrel for internal workpiece fixturing (MandoAdapt), or into a jaw chuck (JawAdapt) that enables larger workpieces, up to almost double the diameter, to be held securely by the same chuck body.
Compared with conventional separate chuck set-ups for multi-turning tasks, MandoAdapt and JawAdapt provide users with a three-in-one lathe workholding system to cover all chucking eventualities at a relatively low-cost, as well as vastly reduced changeover times. Designed exclusively for use with the ultra-accurate collet chuck from Hainbuch, who Leader have represented for over 25 years, both systems maintain the high clamping accuracy for which the Hainbuch system is renowned – guaranteed within 5 micron TIR. Both products are easy and quick to implement; after removing the chuck’s collet, both MandoAdapt and JawAdapt accurately locate via a central location/locking screw and tapered ring mechanism. To revert to normal collet operation, the screw is simply released and the collet re-inserted. The chuck body remains untouched and mounted on the machine at all times, which contributes to the high levels of concentricity consistently achieved.
MandoAdapt is currently available for 42, 52, 65, 80 and 100 mm Hainbuch Modular and Combi pull back chucks, the stationary chuck range MANOK and the manual rotating chuck TOROK, giving a mandrel clamping range of 13 to 100 mm diameter. Soft mandrels can also be supplied, which can be self-machined to suit specific requirements. As its name suggests, JawAdapt converts a collet chuck into a jaw chuck, enabling a 65-mm chuck, for example, to accommodate workpiece diameters of up to 120 mm. Following removal of the standard Hainbuch collet, the chuck collet acts as three master jaws with serrations aiding location accuracy and stroke adjustment of JawAdapt. Location is again via the central screw. JawAdapt is currently available for 65, 80 and 100 mm Hainbuch Combi pull back chucks MANOK and TOROK.
